Description

Technical Field

[0001] The utility model relates to the technical field of fabric tensile performance detection, in particular to a fabric tensile performance detection device. Background Art

[0002] Fabric tensile testing involves slowly pulling a fabric sample under an axial force until it breaks. The purpose of this test is to determine the fabric's tensile strength and elongation. During the tensile test, the deformation of the fabric is observed to determine the fabric's tensile strength level. Testing fabric tensile properties typically requires a fixture to secure the sample at both ends. However, existing fixtures offer poor grip, making the sample prone to falling during stretching, which can affect the test. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0023] like Figures 1-8 As shown, the utility model is a fabric tensile performance testing device, including a base 1, a stand 2 and a stretching mechanism 3, the stand 2 is arranged on the base 1, the stretching mechanism 3 is arranged on the stand 2, the stretching mechanism 3 includes a bidirectional threaded rod 5, a guide rod 6 and two sets of clamping components 7 symmetrically arranged, the bidirectional threaded rod 5 is rotatably arranged on the stand 2, the guide rod 6 is arranged on the stand 2, the clamping component 7 includes a stretching seat 8, an anti-slip roller 9, an arc-shaped splint 10, a sliding rod 11 and a spring 12, the stretching seat 8 is arranged on the bidirectional threaded rod 5 through a threaded sleeve and is slidably sleeved on the guide rod On the rod 6, the anti-slip roller 9 is rotated on the stretching seat 8 through the roller shaft. A sliding cavity is provided in the anti-slip roller 9. The spring 12 is provided in the sliding cavity. The sliding rod 11 is provided on the spring 12 and slides and extends out of the sliding cavity. The arc-shaped splint 10 is provided on the sliding rod 11. A first motor 13 is provided on the stretching seat 8. The output shaft of the first motor 13 is fixedly connected to the roller shaft of the anti-slip roller 9; a second motor 14 is provided on the stand 2, and one end of the bidirectional threaded rod 5 is provided on the output shaft of the second motor 14; a scale line 18 is provided on the stand 2; and a pointer 19 is provided on the stretching seat 8.

[0024] A fixing frame 15 is provided in the middle of the stand 2 and is located between the two groups of clamping components 7. A photoelectric sensor transmitter 16 and a photoelectric sensor receiver 17 are provided on the fixing frame 15 and are arranged opposite to each other.

[0025] A controller 4 is provided on the base 1 , and the controller 4 is electrically connected to the first motor 13 , the second motor 14 , the photoelectric sensor transmitter 16 , and the photoelectric sensor receiver 17 .

[0026] When in use, one end of the fabric sample is first clamped between the anti-skid roller 9 and the arc-shaped clamping plate 10, and then the first motor 13 is started through the controller 4, and the anti-skid roller 9 is driven to rotate by the first motor 13, so that the fabric sample is wound around the anti-skid roller 9 at least once, and then the above operation is repeated to fix the other end of the fabric sample between another set of anti-skid rollers 9 and the arc-shaped clamping plate 10. After the fabric sample is fixed, the second motor 14 is started through the controller 4, so that the second motor 14 drives the bidirectional threaded rod 5 to rotate, and the bidirectional threaded rod 5 drives the two sets of stretching seats 8 to move away from each other. The fabric sample is tensioned, and the indicated position of the pointer 19 on the scale line 18 in the tensioned state is recorded. Then, the second motor 14 is driven to continue rotating, so that the two sets of stretching seats 8 continue to move away from each other to stretch the fabric sample. When the fabric sample breaks, the photoelectric sensor receiver 17 receives the signal from the photoelectric sensor transmitter 16 and transmits the signal to the controller 4. The controller 4 controls the second motor 14 to stop rotating, and then records the indicated position of the pointer 19 on the scale line 18 at this time. In this way, the tensile performance of the fabric sample can be tested, and the test results are more accurate.

[0027] During the stretching process of the fabric sample, since the fabric sample is passed through the top of the arc-shaped clamping plate 10 for at least one circle, the fabric will exert pressure on the arc-shaped clamping plate 10 during stretching. The arc-shaped clamping plate 10 is under pressure and can clamp one end of the fabric sample more firmly between the anti-slip roller 9 and the arc-shaped clamping plate 10. The greater the pulling force, the better the clamping effect on the fabric sample, thereby effectively preventing the fabric sample from falling during the test.

[0028] To sum up, the present scheme is provided with a clamping assembly 7. When clamping the fabric sample, one end of the fabric sample is first clamped between the anti-slip roller 9 and the arc-shaped clamping plate 10, and then the first motor 13 is started. The anti-slip roller 9 is driven to rotate by the first motor 13, so that the fabric sample is wrapped around the anti-slip roller 9 at least once. At this time, when the fabric sample is subjected to a tensile test, the arc-shaped clamping plate 10 will be under pressure, so that one end of the fabric sample can be clamped more firmly between the anti-slip roller 9 and the arc-shaped clamping plate 10. The greater the pulling force, the better the clamping effect of the fabric sample, thereby effectively preventing the fabric sample from falling during the test.
